[Fixed] How to append new FormGroup or FormControl to form


I have the following form in Angular created with FormBuilder:

constructor(private fb: FormBuilder) {
    this.myForm = fb.group({
        'name': ['', [Validators.required],
        'surname': ['', [Validators.required],
        'email': ['', [validateEmail]],
        'address': fb.group({
            'street': [''],
            'housenumber': [''],
            'postcode': ['']
        }, { validator: fullAddressValidator })

Does exist a way to programmatically append new fields such as FormControl or new FormGroup to myForm ?

I mean if I want to add new fields on demand or on some conditions, how to add items to the same form that is created the first time in the constructor?
